The easy solution is of course to add --disable-bzlib --disable-lzma to your configure line, this means that you loose some capabilities. The alternative is that you either copy liblzma.a and libbz2.a to your target systems or extract liblzma.so.5 and libbz2.so.1 with "ar -x" from the archives and copy the resulting shared libraries (untested).

[FFmpeg-user] Problem syncing/lag adaptive bitrate HLS
Hi everyone, I am currently having a problem trying to implement adaptive bitrate of HLS live streams with the help of ffmpeg. I basically have a RTMP source that I'm converting into two HLS playlists: - One is just demuxing and segmenting the video into ts files, - A second of lower quality with audio only, in this case I use the libfaac codec to compress it. Here is what I am executing: #the high quality ffmpeg -i rtmp://localhost/live/$name -bsf:v h264_mp4toannexb -c:a copy -c:v copy -sc_threshold 0 -hls_time 5 -hls_list_size 3 -hls_segment_filename '/live/$name_hi/%d.ts' -hls_allow_cache 0 /live/$name_hi/index.m3u8 #the low quality ffmpeg -i rtmp://localhost/live/$name -async 1 -vsync 1 -ab 55k -bufsize 55k -vn -c:a libfaac -sc_threshold 0 -hls_time 5 -hls_list_size 3 -hls_segment_filename '/live/$name_low/%d.ts' -hls_allow_cache 0 /live/$name_low/index.m3u8 These two playlist are then combined into a global live playlist as recommended by Apple. Everything runs fine and I can perfectly play this global playlist with HTML5 coupled to this flash plugin: https://github.com/mangui/flashls My problem is when I'm playing this playlist with iOS, every once in a while the player presents an initial lag before playing normally, or even displays a black screen with just the sound. It is worth to notice that the segments in the respective playlists do not have the same duration: the high quality playlist #EXTM3U #EXT-X-VERSION:3 #EXT-X-ALLOW-CACHE:NO #EXT-X-TARGETDURATION:6 #EXT-X-MEDIA-SEQUENCE:7 #EXTINF:4.00, 7.ts #EXTINF:6.00, 8.ts #EXTINF:4.00, 9.ts the low quality playlist #EXTM3U #EXT-X-VERSION:3 #EXT-X-ALLOW-CACHE:NO #EXT-X-TARGETDURATION:6 #EXT-X-MEDIA-SEQUENCE:7 #EXTINF:4.992300, 7.ts #EXTINF:4.992289, 8.ts #EXTINF:5.015511, 9.ts When I am playing only the high quality playlist, the playback is perfect. Does it have to do with a misalignement of the keyframes betwseen the two playlists and how can I fix that?

[FFmpeg-user] ffmpeg runtime dependences
Hi, All, We need ffmpeg running in AIX. We have several hosts and have to install GCC to build ffmpeg on each one of them. I hope to build ffmpeg in one machine, and be able to use in other machine with exactly same operating system settings. I have checked the run time dependences, the lib files highlighted in green are existing AIX files, and the only two library files highlighted in red are GCC related. I am wondering if it is possible that we could make the reference to GCC : /opt/freeware/lib/gcc/powerpc-ibm-aix7.1.0.0/4.9.2/../../../liblzma.a(liblzma.so.5) /opt/freeware/lib/gcc/powerpc-ibm-aix7.1.0.0/4.9.2/../../../libbz2.a(libbz2.so.1) At compile time such that we only need to build once in my system? Our AIX hosts are production servers with very high working load. The installation of GCC through RPM package requires root privilege. Our System administrator is afraid of this installation could cause the system unstable or any unpredicted system issue. Thanks for your helps.

Yes, live555 support it according to Q&A (though the recommendation is to use rtp instead). I intend to use mpeg-ts over udp, (with given encoded buffers from HW encoder). Do you think that it is better to do it with ffmpeg for the streaming purpose, or better do it with live555 library instead ? It seems that ffmpeg API is simpler for this but I am not sure if this should work. Another thing - Is the latency for the streaming will be minimal with ffmpeg ? Thank you!

Definitely: Muxing transport streams is not trivial and bugs exist. (I suspect sending data over udp is trivial.)

[FFmpeg-user] ffmpeg - use for mpeg-ts streaming
Hello, I thought to use ffmpeg library to muxing given encoded buffer, and stream into mpeg-ts using udp (doing it in code , not shell). I would like to ask if using ffmpeg for streaming this way is recommended or better using another library for streaming such as live555. I only would like to ask if there are known issues with ffmpeg used for mpeg-ts udp streaming.
