ffmpeg with input mpd does not work (line 453) #6

Closed Lis-TV closed 2 years ago

Lis-TV commented 2 years ago

There are problems. First, the ffmpeg (v 4.2.7) does not work with mpd

ffmpeg -i WMAS\content\avc_sets\12.5_25_50\t1\2022-01-17\stream.mpd -c:v copy -bsf:v trace_headers -f null -

[dash @ 0000022c89e894c0] Failed to open an initialization section in playlist 0 [dash @ 0000022c89e894c0] Error when loading first fragment, playlist 0 WMAS\content\avc_sets\12.5_25_50\t1\2022-01-17\stream.mpd: No such file or directory

I run it using different approach. I just copied init segment and first data segment to mp4 file, then i run: copy /B croatia_L1_1920x1080@25_60_dash_track1_init.mp4+croatia_L1_1920x1080@25_60_dash_track1_0.m4s merged.mp4 ffmpeg -i merged.mp4 -c:v copy -bsf:v trace_headers -f null - > report.txt 2>&1

I believe this issue could also be due to outdated test vectors, that use an old folder/file structure, similar to issue #2

Example of current test vector MPD path: https://dash.akamaized.net/WAVE/vectors/cfhd_sets/12.5_25_50/t1/2022-07-20/stream.mpd

Running the following command: ffmpeg -i stream.mpd -c copy -bsf:v trace_headers -f null - > report.txt 2>&1 from this folder: cfhd_sets/12.5_25_50/t1/2022-07-20/ which contains stream.mpd and where the segments are in the /1 subfolder, results in the expected report being generated.
