...ne. Recently I have been experimenting with Swfdec and Swfdec-mozilla. I started with the latest stable releases and Gstreamer, but I could only get Flash videos to play the video, no sound. However, I don't want Gstreamer, it's too big. Ffmpeg alone has become extremely capable. The 'ffplay' utility (in Ffmpeg, uses SDL) plays almost all my video and audio files. Not quite: using Ffmpeg from svn December 29, 2009, I found that my RealMedia videos played only video no sound -- ffmpeg has the required 'sipr' audio decoder but it doesn't work. They are almost there, ffpla...

Hi all, I?m using icecast2 to serve live streams in mp3. The streams can be played on Chrome or web views on Android, but it is very slow. Then i tried ffplay (ffmpeg) to play the streams, it?s much faster but it reports ?header missing?. I built ffmpeg with debug-info and i saw that ffmpeg probed the streams several times to get the stream format. First several times the score is low and ffmpeg does not have confidence in the probed format. I guess that...

If this is a lab setting, creating a small batch script to fetch the samplerate tag and passing it to a playback program like ffplay doesn't seem a very big deal?

...e permanently, though my solution is most likely not going to be upstreamable in any capacity.) FYI, the third-party decoder is highly compliant according to the spec test suite, producing identical audio playback on almost all of the files, but it also doesn?t verify or error on any checksums. ffplay and ffmpeg both accept the file and can play and transcode it correctly, although they ignore the sample count in the streaminfo header and will read all frames they can find. The latter leads me to believe that checksums are the actual issue, even though flac reports the generic ?Bad Header? and ?...

Hi, I'm one of the Swfdec[1] Flash player developers. As you may be aware, Flash uses VP6 as a possible video decoder. Someone recently grabbed all of the videos at http://pown.alluc.org and threw them at ffmpeg. Surprisingly, lots of them killed the vp6 decoder and in turn my browser. I'll attached a series of patches for issues that I could fix myself, and point out issues I could not

Hello, I have dozens of video files that were encoded using the speex format of audio and can not seem to find any video playback devices that support speex lol. Literally every playback device I've encountered (mac, 10.10.2) plays the videos w no sound. Do you know of any playback devices for the mac format that support speex? -------------- next part -------------- An HTML attachment was

...st attempting to re-encode some 720p HD (720x576) mpeg2-transport files to theora using ffmpeg2theora. However it seems impossible to get the framerate right; if I leave it on default the framerate seems to be doubled, if I force input fps to 50 it seems to go half speed. The files play fine with ffplay however. Has anyone got any clues?

Isn't the FLAC encoder 'tuned' for the compression of audio data at common sample rates anyway? Does it make sense to use FLAC to compress arbitrary analog data at very high sample rates as opposed to other general purpose compression algorithms?
