gst-launch issue with both audio and video
Locked
 
|
I'm trying to decode a .ts file with the line:
gst-launch-1.0 -v filesrc location=/data/file1.ts typefind=true ! tsdemux name=src src. ! queue ! avdec_aac ! audioconvert ! autoaudiosink src. ! queue ! h264parse ! "video/x-h264, alignment=au" ! avdec_h264 ! queue ! "video/x-raw" ! videoconvert ! autovideosink If I run the audio and video parts separately: gst-launch-1.0 -v filesrc location=/data/file1.ts typefind=true ! tsdemux name=src src. ! queue ! avdec_aac ! audioconvert ! autoaudiosink and gst-launch-1.0 -v filesrc location=/data/file1.ts typefind=true ! tsdemux name=src src. ! queue ! h264parse ! "video/x-h264, alignment=au" ! avdec_h264 ! queue ! "video/x-raw" ! videoconvert ! autovideosink each runs successfully. When I use the combined line, it looks like the audio links all the way to autoaudiosink but the video stops after setting up the sink to avdec_h264. What am I missing? The debug output from each of the three runs is below.

Hi John, It could be that the keyframe distance in the MPEG-TS file is fairly large, larger than the ~1 second of buffering that the queue in the other branch provides. Or the bitrate is very high and the video branch queue default limits are too small for that (max 1 sec, 200 buffers, 1 MB). Some things to try: 1) Unset non-time limits on both queues: .. ! queue max-size-buffers=0 max-size-bytes=0 ! .. 2) Increase time limit on both queues, in addition to (1): .. ! queue max-size-time=3000000000 max... ! .. 3) Try decodebin or decodebin3 instead, or even playbin.

Thank you. That solved the problem with the pipeline from the command line.
I'm actually trying to run it from a program so that I can also access the KLV data in the .ts file. When I add the queue parameters to my program, the program provides the following warning: 0:00:00.144022575 11856 0x186f720 WARN mpegtspacketizer mpegtspacketizer.c:2329:mpegts_packetizer_pts_to_ts: No groups, can't calculate timestamp Looking up that message, I found someone that said you needed to add 'tsparse set-timestamps=true' before the tsdemux because " by default the timestamps are not preserved when working with mpeg ts". I've added that to the command line pipeline, which still works, but I still get the error when I run the program with that added. (Of course if the timestamp issue was true,. why do I not get this error when running from gst-launch?) Is there something else I'm missing?
