[FFmpeg-devel] dashenc.c - variables not passwed to "media_seg_name"

2018-08-21 Thread Ibrahim Tachijian
It doesnt seem that ffmpeg is parsing the variables inside media_seg_name when passing my own "-media_seg_name". Can somebody confirm? *Ibrahim Tachijian*CEO Net Sat AB Email: bar...@netsat.se _ *Net Sat AB*Langelandsgatan 8, 164 43 K

and I look at the difference. I am currently considering a stream to be "out of sync" when the difference is above 1. What does difference of 1 in start_pts actually mean? Is it wrong or correct to consider A/V out of sync when there is a difference in start_pts ? -- *Ibrahim Tachijian*

[FFmpeg-devel] Ffmpeg, UDP input source from satellite audio sync issues

2018-06-20 Thread Ibrahim Tachijian
Hey, So this is a problem that has been bugging me for years. 1. The source is udp and the actual source is satellite. 2. Knowing its satellite we also know the stream won't be 100% perfect, there will be losses. 3. Tranacoding with h264 and fdk-aac and outputting to hls. The problem is that aft

[FFmpeg-devel] live_start_index & ignoring "options not found"

2016-12-18 Thread Ibrahim Tachijian
Hey, I use live_start_index to control which segment ffmpeg starts with on a HLS live stream. This is working as expected. However, when the input file is NOT a HLS live stream then using "live_start_index" of course gives you a "Option live_start_index not found" and then quits ffmpeg. I'd like

2016-11-18 Thread Ibrahim Tachijian
Hello, We have problems with long-running ffmpeg processes where the input source is sometimes lossy. The input comes from Satellite and therefore there will always be some loss sometimes, there is nothing we can do about fixing the input. Our issue is that, after lossy input signal, the audio a

[FFmpeg-devel] HLS Input -> tee muxer -> HLS+UDP output

2016-10-14 Thread Ibrahim Tachijian
Hey, When using an HLS input transcoding processes can really be speeded up compared to having a udp input simply because you have a few segments cached and can transcode immediately as fast as CPU allows. This means that ffmpeg will also produce the playlist and first segments really quickly. Th

Hello, I've been thinking about an option for "hls_time" that is not currently supported by FFMpeg and I would like feedback to if some of you may think this is useful or utterly unnecessary. I find scenarios where we sometimes want to create an HLS output and would like the *first couple of segm
