That error happens when avresample_open call fails.  This is going to be some sort of issue with how libav was built as this is known working.

I made a few more tests: the original file has AAC audio, and avconv needs "-strict experimental" option to process that. Probably that's why FreeSWITCH crashes. After I converted the video to 320x240 and MP3 audio, I get a different error: 

2015-07-01 01:46:22.701171 [ERR] avformat.c:1136 Failed to initialize the resampling context

same error if I need to produce 48kHz OPUS or 8kHZ G711.

VLC plays back both the original and converted videos so far.

I'll play around with it during the week.

Depending on what ext you have and the proper build of mod_av I can't comment.

I can confirm with the properly installed debian packages for jessie that at least mp4 files work either by reference to .mp4 files or by using av:///path/to/file.mp4

av:///tmp/somefile.ext crashed the daemon, I didn't yet find the time to analyze it and file a jira.

It was av:// not avformat:// i was remembering the old version.


if av:///tmp/somefile.ext works then it can be added to mod_avformat_load function in avformat.c:1949 ish  to register the extension for convenience.

mod_av doesn't seem to be registering an endpoint, so prefixing avformat:// or av:// does not help. I'll have a closer look later and probably open a Jira

Webm has its own module.  Av and vlc both have broken webm at the time of coding.


mod_vlc can play other formats but they are not registered in the module by file exten however you can use vlc:// syntax.

mp4 is the safest bet because it works in mod_av which is more stable than vlc.  More formats can be added to mod_av as well but I don't remember if its as easy as avformat://<path>

We don't have any choosing best format etc.  It's not going to be a point of focus to squeeze performance out of stuff like that in this stage of development.

by the way, is there a way for playback to select a best matching
encoding, like it does with audio sample rates?
