No, Just merge two workflow into one workflow, fix 7975 next step, just modify the code block at hlsenc_io_open->flush buffer data->hlsenc_io_close. modify to hlsenc_io_open->flush buffer data->check status-> reopen (hlsenc_io_open)->reflush data(option retry times)->hlsenc_io_close. > > I tested it on Windows and it still crashes when attempting to write to a > http server that doesn't support persistent connections: > > [http @ 0000029C0EBAD080] URL read error: End of file > [http @ 0000029C0D410740] Opening 'http://127.0.0.1/stream2.ts' for writing > [http @ 0000029C0EBAD080] URL read error: Error number -10053 occurred > [http @ 0000029C0D410740] Opening 'http://127.0.0.1/stream.m3u8' for writing > av_interleaved_write_frame(): Unknown error > _______________________________________________ > ffmpeg-devel mailing list > ffmpeg-devel@ffmpeg.org > https://ffmpeg.org/mailman/listinfo/ffmpeg-devel > > To unsubscribe, visit link above, or email > ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
