Description

Recently the webm files generated by FFmpeg stopped working in Firefox (although they play fine in Chrome). I've compiled FFmpeg with the latest git of libvpx and x264. Using git bisect, the bad commit is somewhere between 967facb6950549d0cc4e0ba79a056ebc6f93a049 (which configures/compiles with make and produces a bad webm file) and f1fdd208cc0a1fce7aaaf6b0fe72b013525f49e0 (which configures/compiles with make and produces a good webm file). The intermediate commits don't configure properly with the options I use (they complain about an unrecognized --enable-postproc).

I'm compiling ffmpeg with: ./configure --enable-gpl --enable-version3 --enable-nonfree --enable-postproc --enable-libfaac --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libxvid --enable-libspeex --enable-libschroedinger --enable-hwaccel=h264_vaapi && make clean && make

I'm running ffmpeg like: ffmpeg -y -i 7000000009434.mp4 -vcodec libvpx -b:v 800k -bt 400k -vsync 2 -s 640x358 -acodec libvorbis -ac 2 -ar 44100 -ab 48k -async 441000 7000000009434.webm

The mp4 file is a file outputted from an ffmpeg compiled last week.

I'm doing all the compiling on an up-to-date 64-bit Ubuntu 11.10.

Keywords firefox removed

Complete, uncut console output missing.

Is the problem also reproducible with -an / -vn?
Is the problem fixed in the newer revision if you use libavcodec/libvorbis.c (and possibly libavcodec/Makefile) from the older revision?

The console output doesn't reveal much.

Good webm console output (f1fdd208cc0a1fce7aaaf6b0fe72b013525f49e0):

I didn't try to reproduce the problem without video/audio (I need both). Audio does seem to keep playing in Firefox while the video freezes.

I may have time to play with the libvorbis.c tomorrow.

I do have the same problem with ffmpeg version 0.10.2. And the problem is still there even without audio.

Replying to magon:

I do have the same problem with ffmpeg version 0.10.2.

Please test current git head and please provide complete, uncut console output.

And the problem is still there even without audio.

If I understand correctly, please provide output with -an

Ok, tested against current git head(at least I hope it is).

Non of them works in firefox 4 (ffmpeg 0.10.2 video&audio also tested on current firefox).
Every video does play in mplayer. Audio plays in vlc(my VLC seems to not have VP80 codec).

Can you confirm that all three commands produce firefox-playable files with f1fdd20 (git checkout f1fdd20)?

comment:7 Changed 13 months ago by magon

Ok. The problem is still there in f1fdd20. So this seems unrelevant.

I am upgrading firefox right now. When I have current firefox, I will do new tests.

P.S.: But still the firefox 4 is able to play youtube.com webm videos. And also test video from http://videojs.com/.

Ok. Conclusion is simple. Wrong was web server.
I was not suspecting web server at first, because I have used apache AND django development server. Both
looked the same, firefox not working, chrome working.
Solution is to make shure, that webm video is sent with mime-type 'video/webm'. Seems that it is important for firefox, but is unimportant for chrome. It works both for ffmpeg 0.10.2 and for git head, with video & audio. I am still using firefox 4.

Please mark this as invalid. I do apologize.

*MY* bug is still not fixed, nor is it invalid.

I tested just now with recompiling the latest git of libvpx, x264, and ffmpeg (2330eb14). Webm videos still don't play in Firefox (but plays in Chrome). The bug exists whether serving over HTTP, HTTPS, or straight off the filesystem ( file://tmp/7000000009434.webm), and older version off FFmpeg worked fine over both HTTP and HTTPS, so having a mime-type issues are irrelevant to my bug.

A video only webm file works. Webm files with audio (vorbis) fail.

Here is the full output (with video and audio -- freezes):

Did you try with older libvorbis.c ?

comment:12 Changed 13 months ago by MarkRose

Haven't yet. I'll give it a whirl shortly.

comment:13 Changed 13 months ago by MarkRose

Using libvorbis.c from f1fdd208 works. It produces both audio+video and audio only files that work fine.

Audio + video:

Component changed from undetermined to avcodec

Related to e5aab2d.

Which firefox version did you test?

Did you see problems with another playback application?

comment:15 Changed 13 months ago by MarkRose

I tried in Firefox 11 and 12. It doesn't work on any platform (Linux, Mac, Windows).

I haven't seen problems in any other applications that I've tried (Google Chrome, Dragon, VLC, Kaffeine, Totem).
