ffmpeg stream with rtsp udp with high resolution
by JONI JONI 13 Nov '17

13 Nov '17

Hi everybody! I have 2 questions about streaming rtsp udp my ffserver conf: <Stream live.h264> Format rtp Feed feed1.ffm VideoCodec libx264 VideoFrameRate 24 VideoBitRate 60000 VideoSize 1080 x 1920 #AVPresetVideo default #AVPresetVideo baseline AVOptionVideo flags +global_header </Stream> 1)I want to stream static file (264) via rtsp to ffserver and watch with ffplayer with udp . When I watch on this stream with tcp all is fine, I can stream 1080 x 1920. But when I watch on this stream with udp I can't stream 1080 x 1920, because then i will see it with low quality/green screen .. Ican only stream 320x240 what can I do to stream with high resolution and watch it on udp? 2)to stream rtsp udp do i need to run: ffmpeg -i staticFile.h264 http://x.x.x.x:<HttpPort> ? and then when i run ffplay do i need to run: ffplay rtsp://x.x.x.x:<RtspPort>/live.h264 ? thank you all!

Splitting DTS-X from MA/Core
by Simon Strudwick 12 Nov '17

12 Nov '17

Is it possible to remove the X component from a DTS stream, leaving only the MA/Core tracks? Or is there even any point in doing this? I know I can remove the MA from the Core using the dca_core bitstream filter, but there doesn't seem to be an appropriate bsf to keep the core and master without the X stream.

Qt audio tracks muted
by Bouke / VideoToolShed 12 Nov '17

12 Nov '17

When outputting QT with multiple audio tracks, on the first one is flagged as active. Now I found this documented, and ‘should’ be fixed, but it’s still the case. (And it’s bad, as Premiere ignores those tracks.) Anything I can do?

Hardware encoding HEVC video on latest Mac through FFmpeg fails (videotoolbox)

10 Nov '17

Platform : macOS 10.13 Adding a hwenc requires an annoying number of small changes to some FFmpeg files, but main logic is in libavcodec/videotoolboxenc.c I was trying to use -c:v hevc_videotoolbox on my Kaby Lake Mac. Any suggestions to make it work out of the box?

Random repetitions in output
by Mikael Persson 07 Nov '17

07 Nov '17

The command: ffmpeg -i somevideo.someformat %07d.png I would expect this to extract every frame in the sequence and losslessly encode them as png. What actually happens varies with ffmpeg version, 3.3.3 seems to extract all or atleast most frames, but its hard to tell. The version in the ubuntu 16.04 repo instead extracts most or all frames and duplicates a few of them. Sometimes up to 10 x times in a row. Version 3.3.3 also does not extract identical files when run on mac and linux. The difference isnt visible, but the md5sums dont match. I want to extract every frame from the beginning to the end of the video, so this isnt a question of seek accuracy. Is there a command that extracts every single frame, repeatably, regardless of os, input codec etc, without duplicates or skips from a video? Cheers //Mikael

ffmpeg pipe svg image sequence error

With ffmpeg 3.4, you can now render svg image sequences.

Convert a frame to anything readable
by Constantine 07 Nov '17

07 Nov '17

I have a completely broken AVI file that I'd like to restore. It is so bad that apps like DivFix++ don't recognize it. Reading AVI specs gave me a hint that with little heuristics I could extract a frame (FTR: they're stored in chunks starting with FourCC, then size of the chunk, then the data). But what's next? After some googling, I took for experiments a random valid AVI file, and extracted one video frame through radare2. For starters, I'm trying to convert it to jpeg, but I probably do something wrong. Below is the output of ffprobe run on the avi and ffmpeg run on its frame, any ideas? $ ffprobe 1.avi ffprobe version 3.4 Copyright (c) 2007-2017 the FFmpeg developers built with gcc 7.2.0 (GCC) configuration: --prefix=/usr --disable-debug --disable-static --disable- stripping --enable-avisynth --enable-avresample --enable-fontconfig --enable- gmp --enable-gnutls --enable-gpl --enable-ladspa --enable-libass --enable- libbluray --enable-libfreetype --enable-libfribidi --enable-libgsm --enable- libiec61883 --enable-libmodplug --enable-libmp3lame --enable-libopencore_amrnb --enable-libopencore_amrwb --enable-libopenjpeg --enable-libopus --enable- libpulse --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtheora --enable-libv4l2 --enable-libvidstab --enable-libvorbis --enable-libvpx -- enable-libwebp --enable-libx264 --enable-libx265 --enable-libxcb --enable- libxvid --enable-shared --enable-version3 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 libavresample 3. 7. 0 / 3. 7. 0 libswscale 4. 8.100 / 4. 8.100 libswresample 2. 9.100 / 2. 9.100 libpostproc 54. 7.100 / 54. 7.100 Input #0, avi, from '1.avi': Metadata: encoder : Lavf57.83.100 Duration: 00:00:45.03, start: 0.000000, bitrate: 539 kb/s Stream #0:0: Video: vp8 (VP80 / 0x30385056), yuv420p(progressive), 480x640, 527 kb/s, SAR 1:1 DAR 3:4, 60 fps, 60 tbr, 60 tbn, 60 tbc $ ffmpeg -f rawvideo -s 480x640 -pix_fmt yuv420p -vcodec vp8 -i frame out.jpg ffmpeg version 3.4 Copyright (c) 2000-2017 the FFmpeg developers built with gcc 7.2.0 (GCC) configuration: --prefix=/usr --disable-debug --disable-static --disable- stripping --enable-avisynth --enable-avresample --enable-fontconfig --enable- gmp --enable-gnutls --enable-gpl --enable-ladspa --enable-libass --enable- libbluray --enable-libfreetype --enable-libfribidi --enable-libgsm --enable- libiec61883 --enable-libmodplug --enable-libmp3lame --enable-libopencore_amrnb --enable-libopencore_amrwb --enable-libopenjpeg --enable-libopus --enable- libpulse --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtheora --enable-libv4l2 --enable-libvidstab --enable-libvorbis --enable-libvpx -- enable-libwebp --enable-libx264 --enable-libx265 --enable-libxcb --enable- libxvid --enable-shared --enable-version3 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 libavresample 3. 7. 0 / 3. 7. 0 libswscale 4. 8.100 / 4. 8.100 libswresample 2. 9.100 / 2. 9.100 libpostproc 54. 7.100 / 54. 7.100 [rawvideo @ 0x55c1ee9c9760] Estimating duration from bitrate, this may be inaccurate Input #0, rawvideo, from 'frame': Duration: N/A, start: 0.000000, bitrate: 92160 kb/s Stream #0:0: Video: vp8, yuv420p, 480x640, 92160 kb/s, 25 tbr, 25 tbn, 25 tbc Stream mapping: Stream #0:0 -> #0:0 (vp8 (native) -> mjpeg (native)) Press [q] to stop, [?] for help [vp8 @ 0x55c1ee9e05e0] Discarding interframe without a prior keyframe!
