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 <div class="gmail_quote">2008/11/28 Zhao Liang-E3423C <<a href="mailto:E3423C@motorola.com">E3423C@motorola.com</a>> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div> <div dir="ltr" align="left">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.</div> <div> </div> <div>Zhao Liang </div> <div dir="ltr" align="left" lang="en-us"> <hr> From: Julien Pauty [mailto:<a href="mailto:julien.pauty@gmail.com" target="_blank">julien.pauty@gmail.com</a>] Sent: Friday, November 28, 2008 6:48 AM To: Discussion of the development of GStreamer Subject: [gst-devel] Pipeline to convert a transport stream into an AVI file </div><div><div></div><div class="Wj3C7c"> <div></div>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.
