complex filtergraph overlay repeatlast option is broken in Debian static build
by Lukácsy Gergely 05 Feb '14

05 Feb '14

Hi FFmpeg Users! I would like to ask for your help about a Linux-related issue. Yesterday I had dug out my picture-in-picture CLI snippet, and tried it with the latest Debian static build. Unfortunately, the command which worked well with the 1.2.6-Win64 ffmpeg build previously, doesn't provided the expected result on Linux. The basic problem is the following: when I pass two streams with different durations to the overlay filter, the shorter video appears to freezing at the last frame when reaching the end. This behavior can be solved by manually overriding the default repeatlast value ("overlay=[...]:repeatlast=0"), so the short video would simply disappear after reaching it's end. It seems the option have no effect on the newest Debian build, but still working fine with the current Win64 builds. The linux version I tried is: N-39976-g8a3b85f downloaded from http://johnvansickle.com/ffmpeg/, while the Windows version is: N-60366-g6e380cc. (Linux OS: Debian 6.0.8 (kernel: 2.6.32-5-amd64), NT: Win7 pro sp1) The commands I tried is nearly identical on both machines: /home/gergo/ffmpeg-2.1.3-64bit-static/ffmpeg -y -f lavfi -i color=c=0xaa0000:size=640x512:duration=60 -i video_short.flv -filter_complex '[1] scale=640x512 [main]; [0][main] overlay= repeatlast=0' -c:v libx264 -preset medium -pix_fmt yuv420p -b:v 800k -c:a libmp3lame -b:a 96k -threads 0 -f mp4 testbg.mp4 Could you plese point me out what am I doing wrong? Is the daily debian build outdated? Thanks in advance! Sincerely, Gergely Lukácsy.

How to access H.264 MP4 timecode data
by Francois Visagie 05 Feb '14

05 Feb '14

Hi All, I'm trying to access the timecode information stored by my camcorder, but not having any luck. The camera is set to H.264 MP4 recording in this case. According to ExifTool as well as ffprobe and ffmpeg the timecode data is present, but I haven't been able to find a way to extract it. According to the ffprobe manual: ffprobe supports Timecode extraction: * . * MOV timecode is extracted from tmcd track, so is available in the tmcd stream metadata ('-show_streams', see TAG:timecode). I would expect this to extract the timecode stream, but only 1 TAG:timecode value is printed. Also, the "unsupported codec" message does not inspire much confidence that this actually can work: C:\Users\fvisagie\Videos\Home Videos\Testing\AVCHD metadata subtitles>ffprobe -i MVI_0006.MP4 -select_streams 2 -show_streams ffprobe version N-54277-gff130d7 Copyright (c) 2007-2013 the FFmpeg developers built on Jun 30 2013 01:20:12 with gcc 4.7.3 (GCC) configuration: --enable-gpl --enable-version3 --disable-w32threads --enable-avisynth --enable-bzlib --enable-fontconfig --enable-frei0r --enable-gnutls --enab le-iconv --enable-libass --enable-libbluray --enable-libcaca --enable-libfreetype --enable-libgsm --enable-libilbc --enable-libmodplug --enable-libmp3lame --ena ble-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libopus --enable-librtmp --enable-libschroedinger --enable-libsoxr --enable-libsp eex --enable-libtheora --enable-libtwolame --enable-libvo-aacenc --enable-libvo-amrwbenc --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libxavs -- enable-libxvid --enable-zlib libavutil 52. 37.101 / 52. 37.101 libavcodec 55. 17.100 / 55. 17.100 libavformat 55. 10.100 / 55. 10.100 libavdevice 55. 2.100 / 55. 2.100 libavfilter 3. 77.101 / 3. 77.101 libswscale 2. 3.100 / 2. 3.100 libswresample 0. 17.102 / 0. 17.102 libpostproc 52. 3.100 / 52. 3.100 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'MVI_0006.MP4': Metadata: major_brand : mp42 minor_version : 1 compatible_brands: mp42avc1CAEP creation_time : 2014-01-30 17:57:13 timecode : 11:54:27:03 Duration: 00:00:03.84, start: 0.000000, bitrate: 35109 kb/s Stream #0:0(eng): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 1920x1080, 34508 kb/s, 50 fps, 50 tbr, 50k tbn, 100k tbc Metadata: creation_time : 2014-01-30 17:57:13 Stream #0:1(eng): Audio: aac (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 253 kb/s Metadata: creation_time : 2014-01-30 17:57:13 Stream #0:2(eng): Data: none (tmcd / 0x64636D74), 1 kb/s Metadata: creation_time : 2014-01-30 17:57:13 timecode : 11:54:27:03 Unsupported codec with id 0 for input stream 2 [STREAM] index=2 codec_name=unknown codec_long_name=unknown profile=unknown codec_type=data codec_time_base=1/25 codec_tag_string=tmcd codec_tag=0x64636d74 id=N/A r_frame_rate=0/0 avg_frame_rate=0/0 time_base=1/50000 start_pts=0 start_time=0.000000 duration_ts=192000 duration=3.840000 bit_rate=1600 nb_frames=192 nb_read_frames=N/A nb_read_packets=N/A DISPOSITION:default=0 DISPOSITION:dub=0 DISPOSITION:original=0 DISPOSITION:comment=0 DISPOSITION:lyrics=0 DISPOSITION:karaoke=0 DISPOSITION:forced=0 DISPOSITION:hearing_impaired=0 DISPOSITION:visual_impaired=0 DISPOSITION:clean_effects=0 DISPOSITION:attached_pic=0 TAG:creation_time=2014-01-30 17:57:13 TAG:language=eng TAG:timecode=11:54:27:03 [/STREAM] How do I go beyond this to extract the full tmcd stream?

Thank you guys for posting it, I've done just as requested but the dpx that is attached to the mail is stalling it because of it's size. It's awaiting moderation. I've also provided an mxf rendered by our studio with episode using the exact same dpx file. However that one is also awaiting moderation. In the mean time I'll just continue providing links as well to speed up the conversation. The dpx file can be found in the zip file that I refered to in my original post. Here you can find the episode rendered mxf file of the colorbars (Episode rendered mxf colorbars<https://drive.google.com/file/d/0B9hzJJkCcuUrMGZQX19oa1pPREU/edit?usp=shari…> ). And here are the generated waveforms from it: lightworks (lightworks waveform episode rendered mxf colorbars<https://drive.google.com/file/d/0B9hzJJkCcuUrNzFWTGtZenRjLWM/edit?usp=shari…> ) ffmpeg (ffmpeg waveform episode rendered mxf colorbars<https://drive.google.com/file/d/0B9hzJJkCcuUrblVYUGlEajF3cGc/edit?usp=shari…> ) smoke (smoke waveform episode rendered mxf colorbars<https://drive.google.com/file/d/0B9hzJJkCcuUrbDBJbkpueDZDdE0/edit?usp=shari…> ). -- 42

Do the developer need to handle dts/pts or the library ?
by Keestu Pillo 05 Feb '14

05 Feb '14

HI all, I am developing rtsp player in android. Working with fundamentals first. What i did is 1) read the pack 2) Decode it 3) check if (received complete frame ) 3.1 If frame is complete, then Update Texture 4) Event loop 5) Render Copy, Render present. MY Question? 1) Do we need to take care of DTS/PTS while rendering the texture ? With the above logic for few seconds the display is perfect, after which the picture is scrambled. Kindly advice.

OpenCL features
by Ramit Bhalla 04 Feb '14

04 Feb '14

Does anyone know what features will be hardware accellerated when ffmpeg is compiled with --enable-opencl and if any special flags needs to be set? the documentation only seems to refer to deshake filter and some generic options without details. What about libx264, does ffmpeg need to be compiled with opencl to use that flag in x264opts?

Fw: Mixing wav audio and mp4 video
by Zack Thevenot 04 Feb '14

04 Feb '14

I am having trouble mixing a WAV audio file and an audio-less MP4 video file. I am using this command to mix WAV with AVI and WMA files, but it does not work with MP4 files: ffmpeg -i file1.mp4 -i file2.wav -c copy -map 0:0 -map 1:0 output.mp4 -y -report The log file gives this error: "Could not write header for output file #0 (incorrect codec parameters ?): Invalid data found when processing input" I have experimented with many different codecs to fix this, but to no avail. Perhaps the input files I am using are the problem instead? Please let me know how I can accomplish this.

FFMPEG constant bitrate with libvpx on FreeBSD 9
by Manas Bhatnagar 04 Feb '14

04 Feb '14

Hello. I am running ffmpeg version 2.1.1. I am trying to convert a h264,ac3 .mkv to a vp8,ogg .webm file with constant bitrate. the command I am using is "ffmpeg -i video.mkv -c:v libvpx -b:v 450k -minrate 450k -maxrate 450k -c:a libvorbis -b:a 48k -ac 2 video.webm". the output video file that is produced always has a very high bitrate (1000+kbps). I would like some help with making ffmpeg produce a constant bitrate file. the source file has a size of 1280x714 and I am not altering that.

Below you'll find the original logs for the color bar test. The dpx file is number 75 from this image sequence in this zip file (image sequence zip file<https://drive.google.com/file/d/0B9hzJJkCcuUrMmdHdmFodHFiVjQ/edit?usp=shari…> ). I hope this is clear enough. Thank you Carl and Lou for pointing this out.

How to build ffmpeg with OpenCL
by Ramit Bhalla 03 Feb '14

03 Feb '14

I'm trying to figure out how to build ffmpeg with opencl. I add the flag --enable-opencl to the configure. Am using mingw on Ubuntu to build for Win32 and Win64 targets. The configure fails with the following error: configuring ffmpeg_git (/home/mcebuddy/Software/ffmpeg/sandbox/win32/ffmpeg_git) as $ PATH=/home/mcebuddy/Software/ffmpeg/sandbox/mingw-w64-i686/bin:/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games ./configure --arch=x86 --target-os=mingw32 --cross-prefix=/home/mcebuddy/Software/ffmpeg/sandbox/mingw-w64-i686/bin/i686-w64-mingw32- --pkg-config=pkg-config --enable-gpl --enable-libx264 --enable-avisynth --enable-libxvid --enable-libmp3lame --enable-version3 --enable-zlib --enable-librtmp --enable-libvorbis --enable-libtheora --enable-libspeex --enable-libopenjpeg --enable-gnutls --enable-libgsm --enable-libfreetype --enable-libopus --disable-w32threads --enable-frei0r --enable-filter=frei0r --enable-libvo-aacenc --enable-bzlib --enable-libxavs --extra-cflags=-DPTW32_STATIC_LIB --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libvo-amrwbenc --enable-libschroedinger --enable-libvpx --enable-libilbc --enable-iconv --enable-libtwolame --enable-opencl --extra-cflags=-DLIBTWOLAME_STATIC --enable-libmodplug --extra-libs=-lstdc++ --enable-libzvbi --enable-libcaca --prefix=/home/mcebuddy/Software/ffmpeg/sandbox/mingw-w64-i686/i686-w64-mingw32 --enable-static --disable-shared --enable-libsoxr --enable-fontconfig --enable-libass --enable-libutvideo --enable-libbluray --extra-cflags= --enable-nonfree --enable-libfdk-aac --enable-runtime-cpudetect ERROR: opencl not found I've downloaded the OpenCL 1.2 Headers using the guide from: http://streamcomputing.eu/blog/2011-06- ... u-orderly/ into /usr/include/CL anyone have any ideas what's going on?

Full to studio levels
by Rio Kierkels 03 Feb '14

03 Feb '14

Hey everyone, I've been stuck with a level scaling problem. I'm trying to generate broadcast compliant HD mxf files so they have to adhere to the BT.709 spec. Meaning BT.709 primaries with a 2.4ish power function and "studio" luma levels meaning black starts at 16 and white peaks at 235. My sources are full scale BT.709 dpx files. And to force the output to BT.709 primaries I have to add a colormatix filter from bt601 to bt709 strangely enough. It does work however. The only thing I just cant seem to get working is the luma scaling. I've tried the scale filter with the in_range and out_range options. And I've tried the -color_range option on both the in and output files. That does change the pix_fmt indication from yuv420p to yuv420p(tv) but it doesn't change the picture. I've built ffmpeg v 2.1.1 for this project. I hope you guys can help and in time I can help out the project! Rio

VFW versions of FFV1 and ffhuff?
by Timur Zaripov 03 Feb '14

03 Feb '14

Hi, everyone. I am recording gameplay footage using Dxtory and Lagarith codec at the moment. I am interested to try ffmpeg alternatives, but the latest vfw versions that I could find are ffdshow-tryouts (early 2013) and those seem to be bugged (color artifacts on bottom of the screen). Does anyone know about more recent vfw ffmpeg codecs variants? WBR, Timur Zaripov

Convert to a different frame rate smoothly (without jerky playback)
by Don Denton 01 Feb '14

01 Feb '14

I have been using the `-r` option to convert my video to different frame rates, as in this command: ffmpeg -i input.mp4 -r 24 output.mp4 I noticed the playback is incredibly (understandably) jerky, as it seems that ffmpeg simply drops frames to keep the running length the same. I am going from 30fps to 24fps which I know is less than ideal as conversions go. I have used `-vf "fps=24"` to convert as well, and I still get the jerky playback. So my question is this: Does ffmpeg support frame rate conversion that reinterprets the video in any way to create smooth playback? If not, are there other terminal/command line options that anyone knows of that I might be able to use for this final step of my video creation process?

motion detection

hi, i'm looking into motion detection in ffmpeg to see what effect it has on the compression of each frame in a video. my question is: is motion detection is enabled by default?, and if so, how to disable it. thanks in advance! -- View this message in context: http://ffmpeg-users.933282.n4.nabble.com/motion-detection-tp4663518.html Sent from the FFmpeg-users mailing list archive at Nabble.com.
