I tried to upload the 10MB of the stream to upload.ffmpeg.org via FTP but the connection just times out :(:

jsantiago@josepc:~/ffmpeg$ ftp upload.ffmpeg.org
ftp: connect: Connection timed out

Since you reported the problem with ffplay: Is your issue not reproducible with ffmpeg? If it is, please provide ffmpeg output.

We currently have no incoming directory: Can you make the file available somewhere else? (For HD A/V sync issues, you should usually provide significantly more than 10MB.)

After Running the following, VLC can no longer play the output file:

./ffmpeg -i h264-incorrect-dts-pts.ts -vcodec copy -acodec copy out.ts

comment:7 Changed 2 years ago by jlsantiago0

One interesting Note:

I looked at the PTS and DTS returned by av_read_frame() in ffplay and they are not set. ffplay uses av_open_input_file().

However,

I wrote some test code in my own application that uses avio_alloc_context(), av_open_input_stream() where I provide a a 4KB buffer to the AVIOContext, and implement a read_packet() and seek() that uses the C runtime read() and seek() calls and the av_read_frame() returns the correct PTS and DTS for the H.264 stream. It works correctly in this case in my own application using the avio_alloc_context(), av_open_input_stream() interface, but does not work in FFPLAY application.

Reproduced by developer set

Works fine with ffmpeg.

comment:9 Changed 2 years ago by mjs973

This sample bitstream has only I and P frames. The DTS/PTS timestamps in the file look good to me.

This is probably the same issue reported by Tony Strauss on the ffmpeg-devel list on 2011-apr-19 11:46pm, with subject "[FFmpeg-devel] [PATCH]: Fix decoding of mpegts streams with h264 video that does *NOT* have b frames".

Tony thinks the bug is in the h264 parser. He included a patch that has not yet been reviewed.

Fix for h264 I-P only input to decoder

comment:10 Changed 2 years ago by mjs973

I've attached a patch 'fix-no-b-v2.patch' for the h264 decoder that may help this problem, but did not try it with the submitted sample 'h264-incorrect-dts-pts.ts'.

Not fixed by "Fix decoding of mpegts streams with h264 video that does *NOT* have b frames", e12926393b3477e8c324268d3281ae9975f58435

comment:12 Changed 2 years ago by mjs973

It looks like 'h264-incorrect-dts-pts.ts' does not have the (optional) sps.bitstream_restriction_flag set, so we need to use something else to detect that there are no B pictures.

The file does have constraint_set0_flag = 1, which we can use.

I will check if implementing constraint_set0_flag makes this file work.

Detect additional "no B" h264 bitstreams

comment:13 Changed 2 years ago by mjs973

I've attached 'h264-detect-no-b-v1.patch'. I have verified it fixes the submitted sample for latest videolan git.

Test command: ffprobe -show_packets file.ts

comment:14 Changed 2 years ago by michael

sps.constraint_set_flags&1 indicates no B frames
but no B frames does not implicate low_delay=1.

These patches fix the problem. fix-no-b-v2.patch has already been applied to the GIT Tree HEAD. h264-detect-no-b-v1.patch however has not been applied to the GIT Development Tree. Is this intentional?

yes, that patch seems wrong
