FFMEPG - How to resolve 'Reinit context to WxH ... deprecated pixel format'

30 juin 2022, par hi im Bacon

I am using the pyav library to read and process video data and as I am reading through the videos I am getting lots (and lots) of the following output.

I am creating the videos by segmenting either a much larger source file or RTSP/HTTP IP camera.

I would love to understand what this output actually means, and what I can do to prevent its output

ffmpeg creating videos :

ffmpeg -y -i https://manifest.googlevideo.com/api/... -pix_fmt yuvj422p -c:v libx264 -an -vf scale=&#x27;min(1280,iw)&#x27;:&#x27;min(720,ih)&#x27;:force_original_aspect_ratio=decrease -r 12 -vsync cfr -x264opts keyint=12:min-keyint=12 -f segment -segment_format matroska -segment_time 5 -initial_offset 1656497474.686672 -strftime 1 /tmp/tmp87cc1n2o/%Y-%m-%dT%H%M%S.mkv -loglevel error&#xA;

python :

container = av.open(io.BytesIO(...))&#xA;for frame in container.decode(video=0):&#xA;   ...&#xA;

Convert TS-Stream to MKV with ffmpeg [on hold]

17 septembre 2018, par night4awk

I’m using ffmpeg 3.2.7 and I have a problem converting a ts-file lossless to mkv.
The source file is a dumped IPTV-stream recorded with dumprtp (from dvbstream 0.5).

ffmpeg -i Test.ts -map 0:0 -map 0:2 -vcodec copy -acodec copy -f matroska Test.mkv

The convertion is successful, but the output file is pixelated every few seconds.

When I’m converting it with MKVToolnix everything looks fine.

Does anyone has a solution for that problem ?
Maybe some option to sync the stream correctly ?

Here’s a sample output :

# ffmpeg -i Test.ts -map 0:0 -map 0:2 -vcodec copy -acodec copy -f matroska Test.mkv

PyAV/ffmpeg : How to resolve 'Reinit context to WxH ... deprecated pixel format'

26 mai 2023, par hi im Bacon

I am using the pyav library to read and process video data and as I am reading through the videos I am getting lots (and lots) of the following output.

I am creating the videos by segmenting either a much larger source file or RTSP/HTTP IP camera.

I would love to understand what this output actually means, and what I can do to prevent its output

ffmpeg creating videos :

ffmpeg -y -i https://manifest.googlevideo.com/api/... -pix_fmt yuvj422p -c:v libx264 -an -vf scale=&#x27;min(1280,iw)&#x27;:&#x27;min(720,ih)&#x27;:force_original_aspect_ratio=decrease -r 12 -vsync cfr -x264opts keyint=12:min-keyint=12 -f segment -segment_format matroska -segment_time 5 -initial_offset 1656497474.686672 -strftime 1 /tmp/tmp87cc1n2o/%Y-%m-%dT%H%M%S.mkv -loglevel error&#xA;

python :

container = av.open(io.BytesIO(...))&#xA;for frame in container.decode(video=0):&#xA;   ...&#xA;
