MPEG-TS to MP4
Locked
 
|
I am learning about GStreamer, and I have trouble putting together a basic
MPEG-TS to MP4 code. Here is what I have for discover: Analyzing file:///mnt/videos/stream5/test.ts Done discovering file:///mnt/videos/stream5/test.ts Topology: container: MPEG-2 Transport Stream audio: MPEG-1 Layer 2 (MP2) video: MPEG-2 Video Properties: Duration: 0:40:24.615584629 Seekable: yes Live: no Tags: audio codec: MPEG-1 Audio has crc: false channel mode: stereo nominal bitrate: 384000 video codec: MPEG-2 Video I want to transcode it to MP4 and make it 480p(or i is fine too). I think I am close but something is off. I suspect I should not have theoradec and oggdemux ... but confused what it needs to be) (note: I am running on Jetson Xavier thus need to stay away from omxh264enc, etc). This is what I have so far... sudo gst-launch-1.0 filesrc location=test.ts ! oggdemux name=demux qtmux name=mux ! filesink location=test.mp4 demux. ! theoradec ! x264enc ! mux. demux. ! queue max-size-time=5000000000 max-size-buffers=10000 ! vorbisdec ! avenc_aac compliance=-2 ! mux.

oggdemux, theoradec and vorbisdec aren't going to help with what
you're
trying to do here, I suppose you copy pasted these from some example command lines? uridecodebin is probably your best choice here, eg: uridecodebin uri=file:///path/to/test.ts name=d d. ! audio/x-raw ! queue ! avenc_aac ! [..] d. ! video/x-raw ! queue ! x264enc ! [..] On a separate note, on a jetson xavier you should be able to use nvidia's hardware encoders, eg nvv4l2h264enc, not sure where the source for those elements lives but their existence is documented in <https://developer.download.nvidia.com/embedded/L4T/r32-2_Release_v1.0/Accelerated_GStreamer_User_Guide.pdf> On 12/23/20 2:54 AM, KN wrote:

Hi,
You're missing queue elements a bit everywhere. Essentially: * Before N-to-1 elements (muxers) : put a queue on each incoming stream. Ex : demux ! queue ! ... * After 1-to-N elements (demuxers) : put a queue on each outgoing stream Ex: ... ! queue ! mux * Before sink : put a queue before the sinks (unless you already have one just before) Withtout that ... you're trying to run everything in one thread ... and that will deadlock.
