Qualité du média après traitement
21 juin 2013, parLe bon réglage du logiciel qui traite les média est important pour un équilibre entre les partis ( bande passante de l’hébergeur, qualité du média pour le rédacteur et le visiteur, accessibilité pour le visiteur ). Comment régler la qualité de son média ?
Plus la qualité du média est importante, plus la bande passante sera utilisée. Le visiteur avec une connexion internet à petit débit devra attendre plus longtemps. Inversement plus, la qualité du média est pauvre et donc le média devient dégradé voire (...) -

Mjpeg text based subtitle extraction/replay
2 décembre 2013, par user3058117I have an MJPEG based avi file that I cannot replay satisfactorily.
The video I can correctly replay in FFPlay but i cannot replay or demux the text based subtitle stream.
The file contains time/date stamps in the subtitles embedded as ascii text which i can see between the video packets (when viewed in a hex reader).
FFmpeg cannot identify the subtitle codec b7t can see that there is a subtitle stream.
Ive tried a number of filter combinations using GraphStudioNext. I found a couple of working solutions (when previewed in GraphStudio when served to avisynth the subtitles had disappeared again. I checked the filtergraph and the pin out from the avi splitter had misteriously disconnected. I cannot find a way out of this.
Does anyone have any suggestions on how i might demux the subtitle stream(short of writing a converter to extract the text to srt based on the packet timing) ?
This is my first post so apologies if i havent observed etiquette.

Push to another server based on incoming url
1er décembre 2020, par RainmanjamPlaying around with nginx and wanted to know if there was a way to take an incoming RTMP stream and redirect it to another server based on the URL used. For example :


rtmp ://ingress.foo.com/live/ would forward to rtmp ://.internal.foo.com


Thanks.
