Converting MPEG 2 issues
by rava77＠gmx.de 06 Apr '18

06 Apr '18

I have a MPEG 2 file with several audio tracks and one video track. I want to convert it into something smaller, much smaller than MPEG 2, using ffmpeg. I try to create either ogv or mkv containers with good quality and smallest filesize. And I only want to keep the first 2 audio tracks. These can either stay as 6ch or be downmixed into 2ch. My current ffmpeg version is: __________ ffmpeg version 3.4.2 Copyright (c) 2000-2018 the FFmpeg developers built with gcc 7.3.0 (GCC) configuration: --prefix=/usr --libdir=/usr/lib64 --shlibdir=/usr/lib64 --docdir=/usr/doc/ffmpeg-3.4.2/html --mandir=/usr/man --disable-debug --enable-shared --disable-static --enable-pthreads --enable-libtheora --enable-libvorbis --enable-gpl --enable-version3 --enable-postproc --enable-swscale --enable-avfilter --enable-gnutls --enable-libcdio --enable-opengl --arch=x86_64 --enable-libmp3lame --enable-libxvid --enable-libx264 --enable-libspeex --enable-nonfree --enable-librtmp --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libbluray --enable-libass --enable-libopus --enable-libtwolame --enable-libpulse libavutil 55. 78.100 / 55. 78.100 libavcodec 57.107.100 / 57.107.100 libavformat 57. 83.100 / 57. 83.100 libavdevice 57. 10.100 / 57. 10.100 libavfilter 6.107.100 / 6.107.100 libswscale 4. 8.100 / 4. 8.100 libswresample 2. 9.100 / 2. 9.100 libpostproc 54. 7.100 / 54. 7.100 __________ System: slackware based x86-64 Linux. This is the info when playing the original mpeg file using mpv (V 0.27.2) __________ Playing: capture_V0.mpg (+) Video --vid=1 (mpeg2video 720x576 25.000fps) VO: [opengl] 720x576 => 1024x576 yuv420p (+) Video --vid=1 (mpeg2video 720x576 25.000fps) Audio --aid=1 (ac3 6ch 48000Hz) Audio --aid=2 (ac3 6ch 48000Hz) Audio --aid=3 (ac3 6ch 48000Hz) Audio --aid=4 (ac3 2ch 48000Hz) __________ I want to keep audio track 1 ("aid=1") and audio track 2 ("aid=2"), or how ffmpeg usually addresses these: "audio0 audio1" The other 2 audio tracks can be rejected / should not be added into the resulting mkv or ogv. To test if everything works okay I first created some 30 seconds sample video (using stream copy and the same container format than the original, mpg), deleting some video stuff at the beginning I don't want to keep ( thats what the "-ss 1:15.500" is for ) But I don't seem to get it right at all. I read the ffmpeg documentation ( http://ffmpeg.org//ffmpeg.html ), and also some posts about mapping on video.stackexchange.com and superuser.com, still I fail in adding the two audio tracks. Here is how I tried creating the 30 seconds test video: __________ ffmpeg -y -v error -ss 1:15.500 -i capture_V0.mpg -map 0:0 -map 0:1 -c:a ac3 -codec copy -acodec copy -t 30 capture_V1_30s.mpg [mpeg @ 0x2540de0] Invalid media type data for output stream #0 Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument $ ffmpeg -y -v error -ss 1:15.500 -i capture_V0.mpg -map 0 -codec copy -acodec copy -t 30 capture_V1_30s.mpg [mpeg @ 0x1a71b20] Invalid media type data for output stream #0 Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument $ ffmpeg -y -v error -ss 1:15.500 -i capture_V0.mpg -map 0:0 -map 0:1 -codec copy -t 30 capture_V1_30s.mpg [mpeg @ 0xe5fae0] Invalid media type data for output stream #0 Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument __________ All these attempts with mapping failed, so I tried one version without any mapping: __________ time ffmpeg -y -v error -ss 1:15.500 -i capture_V0.mpg -codec copy -t 30 capture_V1_30s.mpg real 0m3.233s user 0m0.911s sys 0m0.811s __________ That /looks/ like it did work… but there is no audio track in the resulting 30 seconds test video: __________ $ mpv capture_V1_30s.mpg Playing: capture_V1_30s.mpg (+) Video --vid=1 (mpeg2video 720x576 25.000fps) VO: [opengl] 720x576 => 1024x576 yuv420p V: 00:00:10 / 00:00:30 (20%) Cache: 10s+11MB __________ Unlike the ffmpeg documentation which says, unless you use the -map options, one video and one audio track is used, the video with the largest resolution, and the audio with the most tracks, and if there are more audio tracks, the one with the lowest index. Which should be in this case: audio 0 (or Audio --aid=1 (ac3 6ch 48000Hz) as mpv calls it). *Why is there no audio when using -codec copy ? Using -codec copy _and_ -acodec copy has the same result: no audio, the resulting mpg only has video.* *What do I do wrong trying to use -map to include the 1st and 2nd audio track (aka audio0 and audio1) ?* There seems to be some glitch in the original capture_V0.mpg file. Playing it with mpv results in mpv updating the info it gives after some seconds at the beginning, and the video played indeed shows some kind of repeat. The video starts, and then it looks like the video starts again, seemingly playing the same video from the start, but the 2nd time it not stopped and results in the start of the actual video that I want to keep - all from "-ss 1:15.500" till the end. Since all that is in the part of the video I want to cut off, it should not be an issue creating the sample videos, and it also should not be an issue creating the real ogv or mkv. The resulting capture_V1_30s.mpg, the one with no sound as described above is indeed the beginning of the video I want to have as ogv or mkv, with everything at the beginning cut off, including the weird repeat-glitch. Cheers Yours truly, Rava

Seeking Programmer
by Beau Sinclair 06 Apr '18

06 Apr '18

I have an immediate need for a programmer who can automate my workflow. I have been told to look into FFMpeg. This is way over my head but the service I provide desperately needs it. Here is an example, I need to be able to film an hour session. Based off of timing data I am getting from a timing system, I want to be able to cut out individual clips from that session as it is going without having to manually move segmented files into Premier or Vegas, create regions, apply pan/crop values, render out new clips, etc... I need a program that can watch my video file grow and take pieces of it that i need with very specific in/out points determined by the data coming from that timing system, apply the same set of pan/crop values to each and place the cuts in a folder, labeled with name data also taken from the timing data. That's it. Can anyone *please* point me in the right direction? Beau Sinclair Business Development Manager Infinity Video Systems Mill Valley, CA Mobile: 828-244-8728 Office: 415-877-4230

Processing multiple udp inputs and outputting to multiple mp4 files
by Jakub Vojáček 05 Apr '18

05 Apr '18

Hello, I have live stream that is running over multiple UDP ip:ports. On each port, there is different content. For example, there is channel BBC and runs on: - 239.200.200.16:1234 only video in resolution 640:360 (A) - 239.200.200.16:1235 same video in resolution 720:410 (B) - 239.200.200.16:1255 audio (C) now we need to capture "event" that lasts for example 10 seconds and product mp4 files with video A, B and audio C. I have tried command ffmpeg -i 'udp://@ 239.200.200.16:1234?interface=172.16.128.42&fifo_size=100000000&timeout=100000000' -i 'udp://@ 239.200.200.16:1235?interface=172.16.128.42&fifo_size=100000000&timeout=100000000' -i 'udp://@ 239.200.200.16:1236?interface=172.16.128.42&fifo_size=100000000&timeout=100000000' -i 'udp://@ 239.200.200.16:1237?interface=172.16.128.42&fifo_size=100000000&timeout=100000000' -i 'udp:// 239.200.200.16:1255?interface=172.16.128.42&fifo_size=100000000&timeout=100000000' -map 0:0 -copyinkf -movflags faststart -t 10 -vcodec copy -f mp4 video_640_360.mp4 -map 1:0 -copyinkf -movflags faststart -t 10 -vcodec copy -f mp4 video_720_410.mp4 -map 4:0 -copyinkf -movflags faststart -t 10 -acodec copy -f mp4 audio_cs.mp4 this creates mp4 files however they are not aligned. When I package this using packager, the content of the two video profiles are not synchronized and audio is not matching any of the videos (when profile is changed, the video jumps few seconds). I think it might be because the ffmpeg first analyses first input, starts recording, analyses second input, starts recording, ... and analysing takes some time, therefore its not synchronized. I also tried multiple ffmpegs, one for each input (something like bash ffmpeg xxx & ffmpeg yyy & ffmpeg zzz). I have achieved much better results than with the first solution but the audio still didnt match video by a little time (usually 0.5 to 2 secs). What would you please suggest to do to achieve having multiple video profiles and audio synchronized from multiple UDP inputs? Thank you for assistance Jakub Vojacek

FFMPEG libx264 not found error
by Niket Joshi 05 Apr '18

05 Apr '18

Hi Team, I am trying to setup ffmpeg enabling libx264 support but I get following error. ./configure --disable-x86asm --enable-libx264 --enable-gpl *ERROR: libx264 not found* If you think configure made a mistake, make sure you are using the latest version from Git. If the latest version fails, report the problem to the ffmpeg-user(a)ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net. Include the log file "ffbuild/config.log" produced by configure as this will help solve the problem. [root@ip-172-31-8-120 ffmpeg]# pwd /usr/local/bin/ffmpeg [root@ip-172-31-8-120 ffmpeg]# !env env | grep PATH PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin I have cloned latest ffmpeg using https://www.ffmpeg.org/download.html. I have /usr/local/bin in ENV PATH and libx264.c in /usr/local/bin/ffmpeg/libavcodec directory. Can you suggest what could be wrong here? Regards, Niket
