[FFmpeg-user] Audio Only Dolby Digital Plus

2018-11-12 Thread Ronak
Hi All, I'm trying to get Ffmpeg to package and generate a valid fMP4 file for HLS of an Audio Only Dolby Digital Plus file. However, the stream that I get is unplayable and has no audio in its sample tables. Here's an example command: ffmpeg -i atmosTest.mp4 -codec copy -hls_time 0.993

Hey All, I noticed that ffmpeg always seems to generate a SIDX box when it's not really required for Audio Only content. Example command: ffmpeg -i atmosTest.mp4 -codec copy -hls_time 0.993 -hls_segment_type fmp4 -hls_flags single_file -hls_playlist_type vod atmosTestffmpeg.m3u8 ffmpeg

So I assume there's no way of making it use HWA automatically via some build parameters without getting into the code, right? I'm using a video source filter which wraps itself around ffmpeg and I need it to do the HWA, which it does not. So if I had an auto-HWA-enabled ffmpeg build, I could

Hi, You need to specify hardware accelerator to ffmpeg. You can give hw acceleration name with -hwaccel option to ffmpeg. And if you want to use it with any binary then its example code is located at : doc/examples/hw_decode.c or doc/examples/vaapi_encode.c or doc/examples/vaapi_decode.c file

Hello, I think this report is interesting. Creating file for broadcast delivery, is not just about having a file which play or doesn't play It's mainly about passing Quality Control. Even if a file can be play in most of software, if it doesn't pass broadcaster QC, it will be reject. In my use
