What is causing "unspecified pixel format" and "Error opening filters !" error in ffmpeg ?
19 février 2019, par SJAndersonLAI’m writing an mp4 to HLS transcoding process that works as intended on files smaller than 7 gigabytes (sample size is 100 videos). When attempting to transcode anything larger than 7GB, it crashes.

Error opening filters!The error says to try increasing
analyzedurationandprobesize, which I set to max value (based on an answer from this post), however that didn’t seem to change the behavior. I also suspected that the file was corrupted, but the fact that this is failing for all files larger than 7GB makes it more difficult to suggest its something not related to the size of the mp4. -

As far as I can see, I notice a difference in codec profileh264 (High 4:4:4 Predictive)vsVideo: h264 (Main)andyuv444pvsyuv420p(tv)and on metadata section.I tried re-encoding the first video with ffmpeg but without success.
Does anyone know why video1 is not compatible with Android and iOS and how to re-ffmpeg it to make it play ?
Thanks ! -
Why does this ffmpeg filter result in an "Invalid Size" error ?
10 avril 2019, par pdoherty926Why do I see this error message :

Invalid argument

ffmpeg -f mp4 -ss 01:24 \
