Hi Folks
I am trying to add decode support for VSF TR-07 (JPEGXS in transport stream),
using the intel JPEGXS project for the codec part. The Intel code gets JPEGXS
working fine in FFMPEG via mkv or mp4 files but it doesnt implement transport
stream support for the new codec so TR07 doesnt work yet
JPEGXS TR07 requires a video descriptor block in the PMT entry for the JPEGXS
pid. feeding in a known good T07 stream, I have successfully parsed that data
in the call parse_stream_identifier_desc() made from pmt_cb() function in
mpegts.c, but its unclear how to connect this metadata I have extracted to the
internal stream which has been created.
Can I inject that newly found video description data into the stream from
inside pmt_cb() ? or does this happen somewhere else ?
As it stands (since I am not actually doing anything with the parsed
descriptor), I still get the error :
mpegts @ 0x7fac96104440] Could not find codec parameters for stream 0 (Video:
jpegxs, 1 reference frame (2[0][0][0] / 0x0032), none): unspecified
sizeConsider increasing the value for the 'analyzeduration' (0) and 'probesize'
(5000000) options
and as you can see, it doesn't get things like the dimensions when summarising
the stream.
INPUT FMT: Video: jpegxs, 1 reference frame (2[0][0][0] / 0x0032), none
Stream #0:0[0x100], 34, 1/90000: Video: jpegxs, 1 reference frame (2[0][0][0]
/ 0x0032), none, 60 fps, 60 tbr, 90k tbn
Metadata:
SRCPID : 256
Could anyone advise how to connect the dots between parsing the PMT and getting
that data into the streams parameters ?
Thanks !!!
