I can capture RTMP, but in certain cases when I go to hls, the chunks lose the video stream
I am capturing 4 channels by RTMP, but there are two channels that capture OK but when I see them for hls I see that the video stream is lost. The channels are America and A24, the rest works OK. In the case of A24 I made a script that generates a m3u8 using the original chunks, not those generated by the hls parameter. In this case those chunks work fine, but browsers can't play it. In the case of America, I left everything as the rest of the channels work, but like A24 the files of the hls seems not to have the full video stream. When I use ffmpeg I see the following:
original chunk (the one generated by rtmp): Stream # 0: 0 [0x100]: Video: h264 (High) ([27] [0] [0] [0] / 0x001B), yuv420p (progressive), 1280x720 [SAR 1: 1 DAR 16: 9], 25 fps, 25 tbr, 90k tbn, 50 tbc
Same chunk hls: Stream # 0: 0 [0x100]: Video: h264 ([27] [0] [0] [0] / 0x001B), none, 25 fps, 25 tbr, 90k tbn, 180k tbc
