Pipeline to convert a transport stream into an AVI file
 
|
Hello,
I'm trying to convert a file containing transport stream into a regular AVI file. Since it's not possible (yet) to seek into a transport stream, I would like to convert it into a format where seeking is supported. My idea was to extract the video and audio streams and then to store them into an AVI container. I made this pipeline: gst-launch avimux name=mux ! filesink location=/tmp/test2.avi filesrc location=257.ts ! mpegtsdemux name=demux demux.video_0078 ! mux.video_00 demux.audio_0082 ! mux.audio_00 This does not work and exits with the following errors: Définition du pipeline à PAUSED... Le pipeline est en phase de PREROLL... ERREUR : de l'élément /GstPipeline:pipeline0/GstFileSrc:filesrc0 : Internal data stream error. Information de débogage supplémentaire : gstbasesrc.c(2234): gst_base_src_loop (): /GstPipeline:pipeline0/GstFileSrc:filesrc0: streaming task paused, reason not-negotiated (-4) ERROR : pipeline refuse to go into setup phase Définition du pipeline à NULL... Libération du pipeline (FREE)... (I translated the main info, rest is in french). I do have a pipeline that convert the file: gst-launch avimux name=mux ! filesink location=/tmp/test2.avi filesrc location=257.ts ! mpegtsdemux name=demux demux.video_0078 ! queue ! mpeg2dec ! ffmpegcolorspace ! mpeg2enc ! queue ! mux.video_00 demux.audio_0082 ! queue ! mad ! audioconvert ! lame ! queue ! mux.audio_00 This one involves decoding and recoding video, which is useless since the formats are the same. I would like to just extract streams and store them into a different container. Is it possible to make such pipeline ? Using avi is not a requirement. I just want to convert the transport stream into a format that supports seeking well.

more debug log needed, especially the caps of mpegtsdemux
srcpads, if these srcpad caps are not compatible with avimux, these elements can
not be connected into one pipeline.

Hello,
Here are the capabilities of avimux and mpegtsdemux: avimux: audio/mpeg SINK template: 'audio_%d' mpegversion: 1 layer: [ 1, 3 ] rate: [ 1000, 96000 ] channels: [ 1, 2 ] audio/mpeg mpegversion: 4 rate: [ 1000, 96000 ] channels: [ 1, 2 ] SINK template: 'video_%d' video/mpeg width: [ 16, 4096 ] height: [ 16, 4096 ] framerate: [ 0/1, 2147483647/1 ] mpegversion: { 1, 2, 4 } systemstream: false mpegtsdemux: audio/mpeg mpegversion: { 1, 4 } video/mpeg mpegversion: { 1, 2, 4 } systemstream: false To me they seem compatible. I'm using the last version of gstreamer. For the mpegtsdemux I'm using the CVS version, only for this plugin though. I wanted to test the very last version. Using the ffdemux_mpegts, I'm able to convert the file, but the sound is bad. It sounds like if the sound is muted several times per second. This is the pipeline i'm using: gst-launch avimux name=mux ! filesink location=/tmp/test2.avi sync=true filesrc location=257.ts do-timestamp=true ! ffdemux_mpegts name=demux demux.video_00 ! 'video/mpeg' ! queue ! mux.video_00 demux.audio_00 ! 'audio/mpeg' ! queue ! mad ! audioconvert ! lame ! queue ! mux.audio_00 Thank you, Julien 2008/11/28 Zhao Liang-E3423C <[hidden email]>
