Other interesting software
13 avril 2011, parWe don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
We don’t know them, we didn’t try them, but you can take a peek.

Qualité du média après traitement

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 (...)

muxing DVB subtitles into transport stream with ffmpeg
28 novembre 2019, par user3439130So i have H264 video + AAC audio muxed inside transport stream (*.ts). To achive evenly spread PCR values i added muxrate tag to my command.
ffmpeg -analyzeduration 20000000 -probesize 20M -loglevel verbose -i 1135084.m4v -i 1135084.m4a -c copy -muxrate 7982K -map 0:v:0 -map 1:a:0 -metadata:s:a:0 language=eng -metadata:s:a:0 tms_track_id=169451954 TEMP0.tsSince our client need DVB substitles we convert SRT to DVD with subtitle edit and then encode them to DVB with ffmpeg with this command :
ffmpeg -analyzeduration 20000000 -probesize 20M -loglevel verbose -i TEMP0.ts -i out.da.idx -map 0 -c copy -muxrate 7992K -map 1:s -c:s:0 dvbsub -metadata:s:s:0 language=dan TEMP1.tshere is output from ffmpeg command :

Playing back the file with VLC i can see that Finish subtitles (between 21:33 and 22:16) are not showing up.Dumping packets from 0:3 track i see that 4 packets have the same DTS/PTS values.

FFmpeg recording works on one laptop but not the other
30 novembre 2019, par Jason TThe following command :
ffmpeg -f dshow -framerate 30 -video_size 640x480 -i video="HD Pro Webcam C920" out.mp4works on one laptop (with C920 LogiTech camera) (Im calling it GOOD LAPTOP). It outputs a recorded video. But it will fail on another laptop (called BAD LAPTOP) and by fail on another I mean - it doesnt output a video (see below for output).
The suggestions are to change parameters based on the specific error that occur on BAD LAPTOP. I have tried many different suggestions but they dont seem to work. Furthermore, they dont provide much insight into the underlying cause of the problem.
Ive used the same camera on both laptops. Im using static windows binaries downloaded from FFmpeg web-site (veranoe). Please note the versions used below were different but that doesnt appear to matter.
Trying to diagnose. Anyone have an idea of where the problem may lie. It seems to indicate a problem at the level of the system / camera setup.
Please note that I’ve updated BAD LAPTOP but still no dice. Also please note that Ive tried this on several systems already and it seems to run ok (i.e., produce an output video)
BAD LAPTOP :
$ ffmpeg -y -f dshow -framerate 30 -video_size 640x480 -t 10 -i video="HD Pro Webcam C920" out.mp4

FFmpeg media info incorrect when encoding aac audio track
11 janvier 2023, par user2028936I recently dipped my feet into encoding with FFmpeg. It's been working fine for me apart form 1 issues I have noticed recently. When I try and re-encode an audio track to acc the media info tags are somewhat wrong. Bitrate, streamsize etc seems to be copied form the source as opposed to reading it from the new track.



Essentially I want to copy the source video, audio and subtitles and also create an AAC version of the soundtrack for playback on devices that don't support HD audio.



Below is an example of what I am doing :



ffmpeg -i source.mkv -map_chapters 0 -map 0:v -c:v copy -c:s copy -map 0:a -c:a:0 copy -map 0:a c:a:1 aac destination.mkv



This results in a media info of :

As you can see the bit rate, stream size, etc is copied from the source track which is incorrect. I've tried the -map_metadata -1 but that removes the metadata without creating a new one and also removed it from all video and audio tracks which I don't want.



Any other ideas what I am doing wrong or is this just a quirk of the software ?



Thanks in advance.



Adding -report output trimming the lines "Writing block of size..." as the file is huge :
