unplayable video

[lomero]

hi everybody, i have 2 video, download on streaming on 2 different site, every video is .ts extension. when play this video on my tv only one play correctly, other video no.
both work on VLC without problem. same video burn with h264 codec.

audio (on video ok): 44.1 kHz, 1 channel, AAC LC (ADTS) (Version 4)
audio (on video NO): 44.1 kHz, 2 channel, AAC LC (ADTS) (Version 4)

this is one shot of video reference:

why this behavior? and to see i need to convert video or only change container?

Could be the profile level (main vs high)

[lomero]

have a way to change profile with ffmpeg without re-encoding all video?

[ProWo]

No

There are tools that let you change the flagged profile and level (without reencoding). That may be enough for the TV to play it.

[ProWo]

What tools?

i have found this to change level profile

ffmpeg -i input.ts -c:v libx264 -profile:v main -level:v 4.0 -c:a copy video.ts

but it's not fast, same time to re-encoding. and try with only one little piece of video and not work on my TV...
now i get to re-encode my video (only solution)

For example, ffmpeg can change the h264 level flag with:

ffmpeg -y -i input.mkv -codec copy -bsf:v h264_metadata=level=3 output.mkv

h264LevelEditor too.

I don't know if any can change the profile flag.

The issue might also be the unusual horizontal resolution of 1712. Though that seems less likely. Remuxing to MP4 or MKV might help also. TVs can be very picky about what they'll play.

Level yes, profile no.

with new encoding on mp4 (no change resolution, copy audio and video) work on my TV
then problem is not resolution maybe...
