I am using mpegts js library for live streaming. We aim to play the live stream urls (.ts format) sent by our users.
The interlaced video below gives a black image in chrome but no problem in firefox
Also the values in mpegjs ts are as follows;
Working;
[TSDemuxer] > Parsed first PMT: {"pid_stream_type":{"256":27,"257":3,"258":6},"common_pids":{"h264":256,"mp3":257},"pes_private_data_pids":{"258":true},"timed_id3_pids":{},"synchronous_klv_pids":{},"asynchronous_klv_pids":{},"scte_35_pids":{},"smpte2038_pids":{},"program_number":1,"version_number":0,"pcr_pid":256}

[TSDemuxer] > Parsed first PMT: {"pid_stream_type":{"256":27,"257":3},"common_pids":{"h264":256,"mp3":257},"pes_private_data_pids":{},"timed_id3_pids":{},"synchronous_klv_pids":{},"asynchronous_klv_pids":{},"scte_35_pids":{},"smpte2038_pids":{},"program_number":1,"version_number":0,"pcr_pid":256}
The only difference between the two is the value 258:6
I can run it in Firefox with the same code, but not in Chrome.
I am not familiar with codecs, remux and demux so I don't know where to start
UPDATE
When I compared the video, I saw that one is field_order: tt in ffprobe and the other is progressive
Below is a comparison of 2 videos
Working video;

- I think this PR will fix your issue. But it is still in draft state. So you need to fork the repo and merge it or manually add the code. – Raghavendra N Commented Mar 2 at 7:33
- @ciaksoy A question about a "not working video" needs an example of that same problematic file (or some bytes of it). Can you share the bytes of the first TS file that you receive and try sending to your player? (see Google for tutorials about how to save an Array or Buffer as a file). – VC.One Commented Mar 5 at 15:27

Reset to default 0Your issue is likely due to keyframe handling rather than the BT.709 color space. Both Chrome and Firefox support H.264 (avc1.640028), and BT.709 color space is standard for HD video. The key difference is how these browsers decode video streams.
Chrome's Media Source Extensions (MSE) expects an IDR (Instantaneous Decoder Refresh) keyframe at the start of the stream. If your TS segment starts in the middle of a GOP (Group of Pictures), Chrome may refuse to decode it, while Firefox might handle it more gracefully.
Also bare in mind that Chrome does not natively support .ts files in <video>. If you're using mpegts.js for transmuxing TS into MP4, Chrome's stricter decoding path may be rejecting the stream due to missing metadata or keyframe alignment.
Configure your encoder to use closed GOPs and force IDR frames at segment starts.
ffprobe -select_streams v -show_frames -show_entries frame=pict_type input.ts | grep pict_type
If the first keyframe isn't IDR, Chrome will likely fail.
