Hi All, We have a HTTP Live Streaming (HLS) setup where we transcode incoming video files to H264 video and AAC audio and build playlist files from that. We want to avoid this step if the input file is already a MP4 file.
I know that MP4 is just a container and does not imply H264 and AAC. I am planning to check the audio and video codec IDs in our program after getting the stream information using avformat_find_stream_info. So, if the video codec ID and Audio codec ID are respectively, AV_CODEC_ID_H264 and AV_CODEC_ID_AAC Is it sufficient to qualify it as a MP4 file? The reason I ask is that there are some flv files that use the same codecs, but I am not sure if it would be safe it to treat it on par with an "authentic" mp4 file. Are there any things that I need to check before concluding that the video is fit for HLS streaming? thanks, Sreenath _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
